"Three-Point Technology and seven-point management" is a famous saying in the Intranet security field. Large enterprises and organizations, small to each of us, are dealing with management all the time. outstanding management is the starting point of enterprise competition and a necessary choice for enterprise success, this has become the consensus of the industry. With the further development of office information technology, enterprises have establi

Firewalls and switches are still commonly used. What will happen to the cooperation between the two? I would like to share it with you here and hope it will be useful to you. With the maturity and rapid development of network and Internet technologies, more and more enterprises and institutions have begun to set up networks to automate office work and share Internet information. However, security issues have also emerged. iMaxNetworks (memory network company) proposed a solution based on the cha

Public network IP and intranet IPFirst, let's take a look at the IP address Division:Class A address:0.0.0.0------127.255.255.255Where 127.255.255.255 is the broadcast address and cannot be assignedClass B Address:128.0.0.0------191.255.255.255Class C Address:192.0.0.0------223.255.255.255Class D Address:224.0.0.0-----239.255.255.255Class E Address:240.0.0.0------255.255.255If you want to see how much IP you have on your machine, you can view it like

Use the intruded vro to enter the Intranet Last year, we started to use vrouters to penetrate the destination intranet. Before seeing wooyun, there was an article about translation of foreigners about routertraffic hijacking. The use conditions were harsh and the results were not very effective. So I decided to write an example of my own test. 0x01 control Router Now we only work on cisco routers, but the

Intranet SecurityIn the face of threats, firewall, anti-virus software, IPS, and other products are often ineffective. These products have been widely deployed in the enterprise network, but these products are mainly for Internet security protection.CAIt is a third-party trust institution that uses the PKI public key infrastructure technology to provide network identity authentication services, is responsible for issuing and managing digital certifica

What is port ing: Port ing (NAT or napt) refers not to a port in the physical sense, but to a port in the TCP/IP protocol. It is a logical port. Port ing: if a computer on the Intranet needs to access the Internet, port ing is required. Port ing is divided into dynamic and static. dynamic port ing: if a computer in the Intranet needs to access xinlang, it will send packets to the NAT gateway, including the

Today, we will talk about how to use port ing without using the gateway to open the Intranet. 　　I. Prerequisites A public IP address is required. Assume that we have a public IP Address: 210.210.21.21. 　　Ii. Tools used 1.lcx.exe 2. vdic 　　Iii. Methods Method 1: Use lcx.exe for ing. (1)we will upload lcx.exe to the public IP address, and execute lcx-listen Port 1 Port 2 in the DOS environment on the public IP Address See lcx-listen 3030 for details. T

Today to tell you how to use the port mapping, not through the Gateway Open intranet method. First, the use of the premise Need to have a public network of IP. If we now have a public network of P, 210.210.21.21 Second, the use of tools 1.lcx.exe 2.vdic Three, method explanation Method one, using Lcx.exe to map (1) We will upload the Lcx.exe to the public network IP, in the public IP on the DOS environment in the implementation of Lcx–listen P

From the first day of commercial use, LAN technology has been adopting an open and shared resource-based model. While pursuing high convenience, security will inevitably be affected, which is also the most important cause for the problem of Intranet security from the beginning. The fineness and depth of management often determine the final level of an Intranet security system. The solutions with higher leve

Intranet SSH forwarding:Upload the tool to a host outside the network:Since the target host is Linux,-listen is followed by the-linux:The SSH client then remotely connects to the host's 3001 port, and the extranet host displays a connection:Then bounce ssh:Outside the network, you can see that the connection has been received:Soon, the SSH client also reacted, stating that the rebound SSH w

First, explain the concept of "intranet" and "Extranet": Intranet: That is to say the LAN, such as the school's local area network, the local area network each computer IP address in this local area network has the mutual opposite sex, is not repeatable. But the intranet IP in two LAN can have the same. Extranet: That is, the Internet, LAN through a server or a r

This article focuses on the direction of Enterprise Intranet security planning. The computer has been facing the public for just over 40 years. The world economy, science and technology and other indicators have developed rapidly. The cultivation of professionals is relatively slow. These problems have emerged and become increasingly serious. Enterprise Intranet security planning first, to do its best Compu

For small and medium-sized enterprise users, viruses, hackers, and malicious attacks are no longer "legends". In the complex and changing network security situation at present, the network system carries the foundation of enterprise operation. The FBI and CSI conducted a special network security survey on 484 companies. The survey results show that more than 85% of security threats come from within the company. In terms of the loss amount, the loss caused by leaks of internal personnel is 16 tim

Question 1: Cross-origin penetrationIn an intranet, the domain administrator permission of Domain a (a. AB .abc.com) has been obtained, and the entire domain has been controlled. Net view/domain: B shows that many machines exist in B domain (B. AB .abc.com). machines in the domain can be pinged to machines in the B domain and want to penetrate machines in the B domain across domains, obtain the domain administrator permission of Domain B.Can I ask the

I have previously shared with you some personal views on the two cutting-edge technologies that may be used in the Intranet security field (sandbox that has not been widely used, and access control that has become more mature, today, I will discuss with you a topic that may be more cutting-edge for domestic enterprises: the threat that mobile device applications pose to Intranet security. Over the past two

First, explain the concepts of "intranet" and "Internet: Intranet: the IP addresses of each computer in a LAN, for example, a School LAN, are mutually exclusive within the LAN. However, the Intranet IP addresses in the two local networks can be the same. Internet: the Internet. The IP address is the only IP address that connects to the Internet through a server o
